LIQUID COATING COMPOSITION.

No Drawing.

To all whom 'it may concern! v Be it known that I, PAUL JAEGER, a subject of the German Emperor, of Stuttgart, in the Kingdom of WViirtemberg, Germany, have invented certain new and useful Improvements in Liquid Coating Compositions, of which the following is a specification.

My invention relates to a liquid coating composition intended more especially for-the finishing of wood surfaces, particularly such as are carved or irregular in contour. The; object of my invention is to provide a combined filler and stain, which will eliminate the difficulties and inconveniences heretofore encountered in the finishing of wood surfaces. Liquid stains, such as have heretofore been used, are objectionable in that they frequently roughen the surface of the wood owing to the swelling of the fibers caused by the carrier. Consequently, the surfaces treated have to be sand-papered, or otherwise smoothed, after having been coated again, because the sand-papering always leaves light spots and strips, especially at the edges. Very porous woods, such as oak, have heretofore sometimes been first mois-- tened with hot Water, allowed todry, then sand-papered and finally filled, which naturally rendered the treatment very expensive." By my invention these difliculties are oversurface-is preventedby the use of my im proved combined fidler' and stain,which consists of the usual color solution to which is added a liquid which prevents the roughening of the surface by filling or closing the pores at the same time as the surface is colored. As such'liquid to be added to the color solution, pyroxylin solutions are particularly adapted, because they have the property of forming a thin, tough, adherent film, more or less colored, when they are cially suitable for the purpose is a mixture of equal quantities of collodion and spirit stain, to which is added a small amount of Specification of Letters Patent.

some fatty substance such as tallow or rosin, or both. As a practical or operative composition, I combine two parts of any suitable spirit stain with one part of'ether in is added to inipart fluidity thereto. A stain produced in this way forms, on account of its fluidity, a penetrating, durable and waterproof colored coating, enough fat or rosin being supplied by the ether solution of the same to put the surface in good condition for further treatment, if desired, such as polishing or varnishing.

By applying a single coat of my composition, with a brush or sponge, a very fine and delicate colorin is produced, which can be subsequently a ded to or modified, if desired. Since, by reason of the rapid evaporation of the composition, more especially of the ether, a very thin but tough, durable surface is produced on the wood before the fibers of the same have time toswell, the surface remains perfectly smooth, and a dull finish can be produced at once, if desired, by brushing, and no sand-'papering or other smoothing is required, whereby naturally great economies of time and money result.

- Having thus described my invention, What I claim is:

1. A combined filler and stain for Wood surfaces and the like, consisting of the mixture of collodion, a spirit stain and .a solution in ether of a fat and rosin.

2. A combined filler and stain for wood surfaces and the like, consisting of the mixture of collodion, a spirit stain and a soluv the presence of. two witnesses. mixed with concentrated'spirit stains. Espel FR. ,JUNGINGER, YT. ELnsz unwioz.
